This plant did very well for a year and bloomed. At some point I think I over watered it and it started looking 'dusty' and then parts turned black. I snipped off the worst parts and let it dry out ...

I received my cactus as a gift approximately 10 years ago. I have never known what species of cactus it is and I thought it is time to figure it out.
I am unfamiliar with cactus and I don't know if ...

It is generally advised against repotting a cactus while it has buds or flowers on it. My Mammillaria prolifera has just finished flowering and it really needs repotting. But since it's a self-fertile ...

I need help identifying one of my old neglected-so-far cacti. Unfortunately and somewhat deservedly, it has not flowered for me yet.
It is the size of an apple (since I have treated it horribly, or ...

Clusters of columnar cacti like the San Pedro (Echinopsis pachanoi) are very appealing to me. I want to grow it all around my house. I am aware however that this is considered to be a hallucinogenic ...

I have been growing this guy for 6 years. He's gotten a little too top heavy and today has fallen over and the top piece (about 9") broke off. The break was very even.
I have no idea where to begin ...

I bought this cactus yesterday. I want to know its name to research how I should take care of it. I'm in a rather cold city (Zanjan in northwestern Iran) with long winters, so I think it's better if I ...

I want to make a standard(1) with scions from a Rhipsalis pilocarpa, or mistletoe cactus. I need a rootstock that:

Is unbranched
Has good longevity (at least 20 years)
Can adapt to high ...

I was given a cutting of a friend's cactus. It is growing in his front yard but he does not know much about it. His cacti are green and segmented some with red bulbs on top. I believe the red bulbs ...

Can I root prickly pear pads that I buy (presumably for food) in the grocery store? It seems like it would be a great way to get some thornless prickly pear cacti growing. If I were to do it, I would ...

I'm in USDA hardiness zone 6b. I'm growing eastern prickly pears as outdoor perennials, and would like to grow some other cacti as well. From what I gather, cold hardiness has a lot to do with soil ...

I bought a cactus from my local big chain DIY store a few years back. It was in a tiny pot and all was well. It's really grown over the years so I decided to re-pot it. I used your everyday compost ...

I recently bought a Schlumbergera from a reputable garden centre. It had buds on it when I bought it. It soon flowered and within a couple of weeks the flowers have all fallen off and the remaining ...

Are eastern prickly pear (Opuntia humifusa) cacti pads as edible as the kind you find in the grocery store (Opuntia ficus-indica)? I know the fruit is edible, if everything across the Internet I've ...

I've been growing a cloned Christmas Cactus now for a few months, and it has been doing quite well. I moved to university 4 days ago (from Swindon, England to Bristol, England) and today I notice that ...

I have a cactus (pictured) which I bought about a month or so ago. It has been slowly drooping, although the tag said to keep it dry in winter and I have only watered it once when I re-potted it. The ...

I've been searching the web online, and the ideas are all conflicting. Some websites would say cacti are unable to grow in glass jars because the heat trapped will cook the cactus, and other websites ...

I received some winter hardy prickly pear pads from a friend last fall. They rooted well, survived the winter well (better than many other plants around here), and are putting out new growth. On the ...

I had a cactus at work since the end of March. It is my first cactus and I don't really know if I was watering it correctly or if I missed something else, but now it's turned yellow and became softer. ...

I just bought a Pink Delight Dragon Fruit. I noticed that all of the cacti at the store had joints, dried flesh that tapers to small point. They seem like a weak point to me, a brittle point that can ...

One of my cactus turned red at its base about a year ago and it has since spread upwards. Some websites say it is a natural ageing process but I doubt so because it is still so small! Now another of ...

I have had a night-blooming Cereus for several years and it has yet to bloom. A friend has one and it blooms no problem. This plant is indoors and keeps growing, but no blooms.
What can I do to make ...

After pruning cacti, I am left with many fallen pieces on the ground which, depending on the cactus type, have varying degrees of difficulty in picking up and disposing of. Is there a standard tool ...

I've had this pair of fairy castle cacti for several years now, and they've done fairly well. However, I noticed today that they have developed brown patches over most of their stems and a few areas ...

Anything in the cactus family can be grafted onto anything else in the cactus family, even jungle cacti to desert cacti. I've even grafted a Schlumbergera to a prickly pear. I would like to know, just ...

I have tried growing rebutias before, and failed because the plants lacked vigor and grew slowly. Would they do better if I flat-grafted it onto a columnar Echinopsis, to increase vigor? Are there any ...

Recently we relocated a cactus into a new flowerpot. When it was planted the soil would evenly occupy the flowerpot and adjoin the flowerpot side walls. The soil isn't cactus soil, but just regular ...
